Brian Singer: "X-Men: Days of Future Past" is biggest film yet

Director Brian Singer claims the brand new chapter of his action franchise about a group of mutant superheroes is going to be the best to date and will be partially set in the 1970s, with former US President Richard Nixon making an appearance.

He told Collider: ''It'll be the biggest movie I've ever made. If you try to do every single detail that's in this story, that can be too much for a movie. But if you can grab the essence of that story and those characters, and then realise it's a movie it's not a comic book so there are certain parameters that are different, it'll still be satisfying to fans and non-fans.

''Part of it takes place in the 1970s. And Richard Nixon's in it, that'll be an interesting casting choice... There'll also be some more science-fiction-type aspects to the story and, without giving it away, some technology that we haven't seen yet in the X-Men universe.''
